VULCANIZER.

Application filed October 30, 1925. Serial No. 65,776.

To all whom it may concern:

Be it known that I, J OHN' FLYNN, a citizen of the United States ofAmerica, and a resident of Akron, in the county of Summit and State ctOhio, have invented certain new and useful Improvements in Vulcanizers,of which the following is a full, clear and exact description.

My invention relates to watch case vulcanizers and the principal objectof my invention is to provide a new and improved vulcanizer of thistype. In the drawings accompanying this specification and forming a partthereof I have shown, for purposes of illustration, one form whlch myinvention may assume. In these drawings:

Figure 1 is front elevation of this illustrative embodiment of myinvention,

Figure 2 is a section on the line 22 of Figure 1, while Figure 3 is afragmentary section on the line 33 of Figure 1.

The vulcanizer herein shown comprises a pair of stationary mold sections11 each provided with a pair of legs 12 arranged to be secured by meansof bolts 13 to a com- 4 mon supporting pedestal 14, and with laterallyextending upper and lower brackets 15 and 16 carrying upper and lowerbearings 17 and 18 in which is rotatably mounted a shaft 19 supportedvertically by means of the adjustable abutment 20 carried by the lowerend of the bearing 18 and itself supporting by means of set screws 21upper and lower arms 22 and 23 which in turn support upper and lowerbrackets 24 and 25 e tending from and a part of a movable mold section26 formed to cooperate with the corresponding stationarymold section 11to form the cavity 42 and to support any desired additional part, suchas the bulls ring 43 used in curing pneumatic tires.

Closing the adjacent faces of the two stationary mold sections 11 are apair of webs 27 provided centrally with alined bosses 41 pierced byalined apertures 23 through which extends a stud 29 supported inposition in the bosses 41 by means of a head 30 and a nut 31 engagingthe outer faces of the two bosses 41, acting in this manner to securetogether the two webs 27 and thus additionally secure togetherthe twostaplate 33, arranged in one position to engage a spider 35 looselysecured by means of bolts 36 to the corresponding movable section26,'closing the centralopening in the outer face of the correspondingmovable mold section 26, effective to transmit to the movable moldsection 26 the thrust imparted to the plate 33 by the nut 34 to forcethe corresponding movable mold section 26 into close proximity with thecooperating stationary mold section 11, and provided with an aperture 37which is closable by means of covers 38 mounted in channels 39 in theribs 40 of the spider 35, and is formed to permit passage of the plate33 when the slides 38 are withdrawn and the plate 33 is in the positionindicated in dotted lines in Figure 1.

The outer faces of each movable mold section 26 may be provided withsuitable pockets 44 for the reception of heat insulating materialintended to decrease radiation from the mold, and these pockets 44 maybe closed by suitable covers 45. In addition, the entire exteriorperiphery of the mold may be covered with similar heat insulatingmaterial to thus decrease such radiation from that surface.

In operation, the article to be cured is placed within the cavity of oneof the stationary mold sections 11, the corresponding movable moldsection 26 is swung into position, the plate 33 is rotated into theposition shown in full lines in Figurel and in which it will engage thespider 35, and the nut 34 is actuated to act through the plate 33 andspider 35 to move the movable mold section 26 into position tightlyagainst the cooperating stationary n old section 11, the necessaryadjustment between the spider 35 and s the movable mold section 26occurring b slippage of the spider 35 onthe mold sec by slippage of theplate 33 on the spider 35 and nut 34-, and the spider 35 serving to sealthe central opening in the outer face of the movable mold section 26 andalso, because of the presence of the Webs -27, to close the space Withinthat mold regardless of the condition or position of the movable moldmember 26 cooperating with the other stationary mold member 11. Onopening, the nut 34 is backed off a sufficient amount to ermit rotationof the plate 33 into the dotted position after which the movable moldsection 26 may be swung open without further actuation of the nut 34.

From the above description it will be obvious to those skilled in theart that the embodiment of my invention herein disclosed provides awatch case heater accomplishing the objects of my invention and superiorparticularly in the method of clamping the movable section in positionon the corresponding stationary mold section, the method offiddltlODilll securing the stationary mold sections toget er, and themethod of segregating the s ace within the mold to revent radiation ofeat from the inner perip cry of the mold.

It will also be apparent to those skilled in the art that the embodimentof my invention herein disclosed embodies advantages other than thosespecifically pointed out or suggested herein, and also that thisparticular embodiment of my invention may be variously changed andmodified without departing from the spirit of my invention orsacrificing the advantages thereof. It will therefore be understood thatthis disclosure is i1- lustrative only and that my invention is notlimited thereto.
